Charcoal Slate vs Thunder Clouds
Where Charcoal Slate belongs to Benjamin Moore's range, Thunder Clouds is a Dulux color. These are both greys, so the question isn't which hue to choose — it's where within grey to land. Thunder Clouds (LRV 17) reflects noticeably more light than Charcoal Slate (LRV 13), a difference of 4 points that becomes especially apparent in rooms with limited natural light. Both lean neutral, so they'll behave similarly in mixed or changing light conditions. At ΔE 1.3, these are close — the kind of difference that matters when choosing between them, but doesn't read strongly in a finished room. Below, 5 simulated room previews show how each color reads at scale — real-room photos will be added as they become available.

Digital color is approximate. These simulations are generated from the manufacturer's hex values and overlaid on grayscale room photos — your screen's calibration, brightness, and viewing angle all affect how they render. Before committing to either color, test physical samples in your own space under the light you actually live with.
